Indiana’s voter registration lists are bloated and the cards are the first step in a $2.1 million process to remove ineligible voters from the lists, according to a report from the Indianapolis Star.

Officials hope to pare down the lists to remove voters who have moved out of state or are dead without disenfranchising voters who have changed addresses or haven’t voted in a while, according to the Star.

The cards were mailed to 4.4 million Indiana voters last week. If you received one of these cards, no action is required.

A second round of postcards will be sent in June to addresses that came back as undeliverable in the first round of cards. Voters will be asked to visit www.IndianaVoters.com to make sure they are registered and update their information. If no response is received, they will be considered inactive.

These inactive voters can still vote in November and in the 2015 and 2016 elections.

Counties will begin removing inactive voters from their lists in 2017 if they haven’t voted since 2014 and haven’t updated their addresses.

The Secretary of State last cleaned up voter lists in 2006 and purged about 300,000 names in that sweep, the Star reported.
